they have a "wedge" to move from ALT/AZ to make it a equatorial........I want to do long exposure photowork.........is this the right path and solution ?

here is a review off of amazon.
Received the wedge in great shape two days after order placed. It requires minimal assembly with no problems and is ready for use in about 20 minutes. The wedgle is very well built and engineered to do exactly what it is supposed to do and that is, convert an Alt-Azimuth mounted telescope into a an equatorial mounted scope. The whole idea is to eliminate field rotation when doing long exposure imaging.
The wedge is placed on the tripod head and attached by 3 cap screws and holds it securely. There are two possible orientations on the tripod head during install, one better than the other. The top of the Celestron tripod has a triangular face. You will want to place the wedge with one of the points of the triangle oriented toward the rear of the wedge. In that way, during the install on the tripod, the wedge will NOT fall off prior to inserting the 3 cap screws. The other orientation (with a flat side of the triangle oriented to the back of the wedge) will allow the wedge to fall off the head prior to seating it with the screws.
Putting the C-11 scope on the wedge has different ergonomics than the placement of the scope in alt/azimuth mode, for sure. Initially somewhat difficult, you will quickly develop the right technique to do it and it becomes a non issue.
The adjustments for alignment on the Pole star absolutely solid. Very good!
Performance in equatorial mode is perfect! Love it. My first effort so far was a series of video images of Jupiter. The planet was low in the sky so resolutions were not optimal. In spite of that a series of decent 20 second video clips and a bit of massaging in Registax, yielded some detail. See attached.
The wedgle works great. Fine product, heavy duty and solid, nicely engineered.
